MACHINE FOR APLYING REINFORCEMENT'TO ISOLES.

Specication of Letters Patent.

Patented J an. 2, 1917.

Application filed December `28, 1911. Serial No. 668,257.

rIhe Object of the present invention is to.

provide a machine capable of applying a reinforcing strip Vin the angle between an npstanding rib or channelflip on an insole and the surface of the sole within said lip. The particular insole upon which this machine is designed to act is channeled from a line well within the edges of the sole outwardly toward such edges, and the flapl formed by channeling is turned up. This leaves a depression in the face of the sole on the inner side of the lip, which Vdepression is equal in width to the .height of the lip, and in depth to the thickness of the lip. The purpose of the machine in which my present invention is embodied is to place a reinforcing strip in this depression and against the inner face of the lip.

To this end the machinecomprises, essentially, guiding means for the reinforcing strip, a device for crowding the strip into the angle, between the lip and the face of the sole, and means for supporting and feeding the sole while the-strip is in process of being applied.

A possible embodiment of the invention, which at the present time I consider preferable to others is illustrated in the accompanying drawings, -in which,

Figure 1 represents a side elevation of the machine. Fig. 2 is a plan view. Fig. 3 is a rear elevation. Fig. 4 is a side elevation of the operative elements ofthe machine as seen from the Side opposite to that represented in Fig. 1. Fig. 5 is a plan View of the same elements. Fig. 6 is a sectional view of the same elements on line 6-6 of Fig. 4. Fig. 7 is a cross-section of the strip guide taken on line 7-7 of Fig. 6.

The same reference characters vindicate the same parts in all the figures.

Referring to the drawings, 1 represents the frame of the machine which is adapted to be set upon a'bench or table. This frame is provided with bearings 2, 3 in which Vis ROLLINs, i

rotatably held a shaft 4, and with an inclined bearing 5y containing the shaft of an inclined work-supporting and feeding member (i, which is here shown as a table having a plane supporting face perpendicular to its aXis. The shaft 4 carries a bevel gear 7 which meshes with a complemental bevel gear 8 on the shaft of the table and imparts rotation to the latter.

The drive to the shaft 4 is through a belt pulley or other driving element 9, a shaft 10,

y carrying a worm 1l, and a worm wheel 12 secured to the shaft 4 and meshing with the wormll. The pulley 9 is loose on the shaft and may be connected therewith when the machine is to be set in motion, byI a clutching device under the control of the operator. Such clutching device is not part of the present invention and may be any of the known forms of clutch. The one which I have chosen for my purpose is a simple form of friction clutch consisting of a disk 13 secured upon the shaft and having a facing 14 of frictional material such as leather. The pulley 9 is adapted to be pressed against this facing and is therefore Slidingly mounted on the shaft, and is controlled by a bell crank 15 pivoted upon a bracket 16, and a treadle 17 connected with the vbelLcrank by a link 18. One of the arms' ofthe bell crank has studs 19 projecting into a groove 20 in the hub of the pulley. Springs 21 and 22 actingon the bell crank and treadle respectively tend to disconnect the clutch, making the machine normally inoperative. The link 18 passes through the table on which the machinel is set and the treadle is pivoted to a bracket 23 secured 'to the floor, in easy reach of the operators foot. v

The tool or element which performs the work of tucking the reinforcingv strip into the angle between the channel lip and the face of the sole is conveniently a disk or wheel 24 which is so arranged lrelatively to the table 6 that its peripheryL can enter the angle referred to, which, for-convenience of v description I prefer to call the inner lip angle, Of an insole properly placed upon the table. This disk is `driven positively in unison with the table and in relatively the same direction by a gear wheel 25 secured upon'the shaft 4 which meshes with a pinion 26 secured upon the shaft 27 which carries the disk 24. For convenience of description I may term wheel.,

rl`he shaft 27 is held in a bearing 28 on an arm 29 Which'is adapted to swing about a pivot stud 30 secured in a bracket 3l which rises from the frame 1. In order to stitfen theJ bearing which the arm 29 has 34 Von the bracket 3l provides a variable limit for .the movement ofthe swinging' arm in one direction. A spring 35 connected at one end to an eye 36 on the maf chine frame, and at the other endv to theA swinging arm'29, normally holds such arm yieldinglyagamst the stop 83 and thereby retains the swinging arm andthe setting wheel 24 in the position shown in F ig. .1.

rhisspring is indicated as broken away-in Fig, 1,. in order not .to obscure the parts behind it. The. connection ofv the spring with the swinging arm 29 provides for an adjustment of the tension of the spring and is eifected conveniently in. the following manner.l An eye bolt 37 is connected to the spring and passesthrough alug 38 projecting from a portion of the arm 29. A thumb nut 39 on the eye bolt enables .the same to be drawn through the. lug 38 to a greater or less extent, and' thereby to stretcher. slacken the spring.

It is necessary to lift theisetting wheel whenever work isplaced in or taken from the machine. by a treadle 40 (see Fig. 3), which is connectedthrough a link 4l with alever 42 pivoted'upon astud 43 and having an arm lying under a foot'44 on the arm 29. As will be readily understood depression of the ytreadle40 causes the setting wheel to be first swung to the right and then upwardly with reference to Fig. l) far enough to widen vthe space between the setting wheel and the table.

Adjacent to the table is a support or guide for the edge of the sole, such guide being a 'roll mounted so as to turn freely` upon an uprightpivot. It is so grooved as.

to provide a conical face, which-is located close to the edge of the table 6 at one point,

and at thispoint is approximately perpendicular to the plane ofV the table. The movement `of .the setting disk away from the table also takes it away fronitlie guide. The nal element to be described' is a such disk or wheel the setting This lifting is accomplished.

guide for the reinforcing strip. Such strip guide consistsv of a'block 46 mounted adjustably on a projection 47 extending from the armk 29. Such bl'ock has a tail 4S extending Vclos-e to the setting wheel vand notched at its end to admit the rim of the wheel. vThe guideway Vfor 'the strip is formed between two flanges 49, which flanges have lips 50 projecting toward one another in that portion of their length nearest to the wheel.,Y The reinforcing strip, represented at .51, which is preferably Va strip of heavy cloth such as canvas, coated on one side with an adhesive, is fedY through the guideway to and under the setting wheel.

Figs. 4, 5 and G Vshow an insole 52 in operative position, with anV upturned channel lip 53 and a channel: 54.V inside of the lip. The reinforcing strip isintended to fill this channel and to lie against theinner face of the lip, extending' preferably. to the outerY edge of thelatter. The sole is placed flat on the table 6 with its'smooth or unchan-` neled face, that is, thesurface opposite'to i the one from which the lip projects against the table, andrits edge against the guide roll y45, the setting wheel having been lifted in the. manner described. The sole is so placedpthat the beginning point of the chan- 1 nel lies directly in front vof the setting' wheel', and the heel portion of the sole projects in the direction of feed. The set-v ting wheel with the reinforcing strip placed under it isthen allowed to return to normal position, in which itis held Vby the spring 35 with its v`rim pressing intothe angle formed.Y by the channel lip. Preferably such rim is brought to affine edge, in order that .it may enterv well into the angle. Thereupon the machine is set in motion and the simultaneous rotation of the table 9 and setting wheel causes the sole and the reinforcing strip to Ybe fed in unison, the` strip being drawn through the guide and laid in the channel. It should be noted that in' order toobtain'this result the setting wheel is arranged with the plane of its rim approximately vertical and the table is on a slant of approximately 45o v,upwardly and outwardly from the setting wheel, whereby the plane of the setting wheel makes an acute angle with th`e` face, or supporting element, vof the table.

Another point of importance to be noted is that the setting wheel does not bear on the face of the sole or press against the lin, but bears only in the angle between the lip and the face ofthe sole.V This will be recognized from an inespection of Fig. 4, which showsthe point clearly.' Although the sole edge guide 45 has a` flange adjacent to the lip, yet this flange is at such a distance from the setting wheel that the lip isunconiined and is subjected 'to 'no pressureV whatever,

except such slight pressure as its own stiness causes it to exert' against the setting wheel, which is inappreciable. In fact the face of the setting wheel might be even more sharply beveled than as here shown without changing in any way its effect on the work. The point is that the wheel is designed to bear only on the center line of the strip and press this center line in the lip angle. v I have found that better results are secured in this. way, asl the reinforceeis tucked more completely and more firmly into the lip angle andV its sides adhere'sufliciently to the lip and to the face of the sole. It is to be noted that the guide 45 is notin any sense a support for the channel lip, but solely a guide for guiding the edge of the sole.

Another important feature is that the settingwheel is so placed that an imaginary line drawn to it from the pivot 30 is approximately perpendicular to the face of the table 6. In consequence the commencement of movement of the wheel away from the guide l5 is perpendicular to such imaginary line, and therefore approximately parallel to the table, hence a. certain amount of such movement is permitted before the distance between the wheel and table vincreases-to any appreciable degree. This arrangement is provided in order to accommodate variations in the amount by which the edge of the sole projects beyond the lip. It is to be remembered that the distance between the lip and the edge of the sole is least at the part which lies outside of the ball of the foot, is greater at the toe, and greatest at the shank. As the sole is fed past the guide 45 those portions of the base of the lip which lie more or less remote from the edge of the sole cause the setting wheel to move slightly toward and from the guide, but in this movement the distance of the setting wheel from the table is not appreciably increased and so the wheel is not withdrawn from the lip angle, and no additional pressure is brought to bear against the lip.
